A marvelous plant known to the Arabs as the Golden
Plant, which is supposed to grow on Mount Libanus, underneath
the road that leads to Damascus. It is said to flower in the
month of May, after the melting of the snow. At night it can be
seen by torchlight, but through the day it is invisible. It was believed
to be of great assistance to alchemists in the transmutation
of metals. It is alluded to by the historian Josephus (Lib.
8, Chap. 25.)
